Earlier today, Apple released iOS and tvOS 11.2.1, fixing a critical HomeKit vulnerability. The update wasn't available for those that are on the beta programs, and now we know why. The company has now released the first developer betas of iOS 11.2.5, watchOS 4.2.2, and tvOS 11.2.5.
The version numbers are certainly worth noting, as they all imply that Apple is planning to release multiple updates between now and when these actually hit general availability. This is actually pretty rare, and one might wonder just what the company needs to fix.
You won't find any new front-facing features in these updates; they focus on bug fixes and stability improvements, as their version numbers imply. For iOS 11.2.5 build 15D5037e, there are a few known issues that have to do with ARKit, Foundation, Vision, and Xcode.
Interestingly, watchOS 4.2.2 build 15S5530d actually says that there are no known issues. For tvOS 11.2.5 build 15K5531d, it only has a single known issue that has to do with Foundation.
If you're on the iOS or tvOS public beta programs, you should see these before the end of the week. If you're looking for a macOS High Sierra beta, that was offered earlier this week.
